Thanks to all the team for working bringing further our beloved IMAP server.
I read the release notes and got caught by this statement:
"Under delete_mode: delayed, only the 20 most recently deleted mailboxes are
kept for any given name."
Not being a native English speaker I may have not a clear idea of the
meaning of "for any given name", so I ask for a clarification.
Is it "20 most recently deleted mailboxes regardless of their name"?
Or is it "20 most recently deleted mailboxes with the same name"? "... same
Or something else?
In practice,
1) what happens if thirty users delete one mailbox each, all with different
2) what happens if we remove 100 accounts and all their tree (dm
user/.<xyz> 100 times)?
We rely on keeping deleted messages and mailboxes/folders for few days on
the filesystem so that recoveries do not hit the backup guys, but can be
operated with a simple wrapper to unexpunge.
Thank you for clarifications,
